2287 dnl We need to decide at configure time if GLib will use real atomic
2288 dnl operations ("lock free") or emulated ones with a mutex. This is
2289 dnl because we must put this information in glibconfig.h so we know if
2290 dnl it is safe or not to inline using compiler intrinsics directly from
2291 dnl the header.
2292 dnl
2293 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2294 dnl user is interested in knowing if they can use the atomic ops across
2295 dnl processes.
2296 dnl
2297 dnl We can currently support the atomic ops natively when building GLib
2298 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2299 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2300 dnl we are using GCC (and not mingw*).
2301 dnl
2302 dnl Note that the atomic ops are only available with GCC on x86 when
2303 dnl using -march=i486 or higher. If we detect that the atomic ops are
2304 dnl not available but would be available given the right flags, we want
2305 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2306 dnl that then to silently fall back on emulated atomic ops just because
2307 dnl the user had the wrong build environment.
2309 dnl We may add other compilers here in the future...
